USAIN BOLT blazed into the history books last night as he again sprinted to gold medal glory.

The 25-year-old became the first man to do the double double – winning both the 100m and 200m titles in consecutive Olympics.

Prince Harry gasped in awe as Lightning Bolt struck twice and blitzed his rivals in a stunning time of 19.32 seconds to take the gold medal.

Chelsea star Frank Lampard and fiancee Christine Bleakley cheered the sprint king on as he came close to his own Olympic record time of 19.3 seconds.

The 80,000 capacity crowd inside the Olympic Stadium went wild as the Jamaican again rewrote the history books with his awesome ability.

After his win, Bolt sprinted round the track in a lap of honour and did push-ups before pulling his famous Lightning Bolt pose.

He defended the title he won in Beijing four years ago and now has four individual golds.

After a strong start, he quickly exploded away from his rivals to take his place in history.

And it was a clean sweep for Jamaica as Bolt’s countrymen Yohan Blake took silver and Warren Weir claimed bronze.

Bolt said: “This is what I wanted and I got it. I’m very proud of myself.

“After a rough season, I came out here and did it. I thought the world record was possible.

“I guess I was fast but not fit enough. I could feel my back strain a little bit, so all I did was to keep my form. London meant so much to me.”

US athletics legend Michael Johnson said: “He is the best there has ever been.”

Darren Campbell, double Olympic medallist, said: “Legend, legend, legend. It’s cemented. It was over in 10 seconds because Bolt’s start was amazing. Blake pushed him all the way but it is the Usain Bolt show.”

And Olympic silver medallist Steve Cram added: “Gold all the way. Bolt is unique, and he has no equal.

“He is just incomparable in the world of sprinting.”

Before the race began, cocky Bolt looked supremely confident as he played up to the cameras to unsettle his rivals.

He had predicted his own success, saying training partner Blake would never beat him.

He said: “Blake is great. I heard he’s saying a few things about the 200m. But I’ve told him, ‘No chance’. I’m not going to let him beat me over 200m. It’s my main event” After winning the 100m race on Sunday in 9.63 seconds, Bolt had promised another spectacular performance.

Asked about those who doubted his ability before his first triumph, Bolt said: “I told people that when it comes to the championships, it’s all about business for me and I bring it.”

And he paid tribute to the incredible crowd who had screamed him on and said: “It was wonderful.

“I knew would be like this, I can feel that energy and I am extremely happy.”

The BBC’s viewing figures rocketed as the nation tuned in to watch one of the most hotly-anticipated races of the Games.

On Wednesday, just under 11million viewers – nearly half the available TV audience – watched Bolt race in the semi-finals. Bolt and Blake are expected to continue their rivalry and the star has not ruled out defending his titles in four years in Rio. He said: “I hope I’m there.

“I’m going to be 30 and I hope I’m still in good shape.

“Yohan will be 26, so it should be interesting. I’m looking forward to that.”

Bolt prepared for the Games with the rest of his Jamaican track and field stars in Birmingham.

The squad stayed in Birmingham University halls of residence, which were fitted with an extra-long bed to accommodate Bolt.

He will go on now to defend his 4 x 100 metre Olympic title, also won in Beijing four years ago, on Saturday.
